中文摘要
:
泛在电力物联网是我国电网发展的最新方向，从特征来看，其作为信息流与电力流高度耦合的复杂系统——信息物理系统( cyber physical system，CPS) ，从关键节点辨识的角度开展安全防范研究至关重要。以变电站自动化系统(substation automation system, SAS)为研究对象，提出了一种基于改进超图的SAS关键要素辨识方法。分析选取了SAS逻辑拓扑图中适用于逻辑结构分析的两类中心性指标，将其扩展定义到超图中并对比分析各节点的排序差异。从逻辑节点失效和电力系统负荷损失两个角度定义了SAS工作有效性指标和电力CP效能损失指标，从而评价某一逻辑节点工作异常的影响。并应用IEEE 14节点系统进行了算例分析。该方法可获得SAS中物理域和逻辑域交集上的关键逻辑节点排序，辨识出与电力 CPS的静态网络安全相关的重要逻辑节点。
